Food Fraud Quick Bites

“Natural Flavor” Claims

The company that produces the very popular flavored sparkling water brand LaCroix is facing a class action lawsuit that alleges false claims of the product being “all natural.” The suit alleges that certain flavor chemicals used in the beverage are, in fact, artificial ingredients. These flavor chemicals include limonene, linalyl propionate (linalool propionate), linalool and ethyl butyrate (ethyl butanoate). While these flavor chemicals can be synthesized, they are naturally occurring chemical constituents and can therefore be derived from natural sources.

The safety of the beverages is not at issue; this is a labeling question. The suit states that linalool is “used in cockroach insecticide,” which is inflammatory and misleading. Chemical compounds, including those used as food ingredients, naturally have multiple applications and this does not have any bearing on the question of whether they are safe to use in foods.

Presumably, the labeling issue of whether these flavor chemicals were naturally or synthetically derived will be addressed as the suit progresses. This suit does, however, highlight some of the challenges we have in tracking food fraud information related to flavors.

Flavors are big business. Appealing flavors enabled LaCroix to make unsweetened sparkling water explode in popularity. If you have been on the Institute of Food Technologists Annual Meeting expo floor, you have seen the prominent displays and creative food samples offered up by the big flavor houses. It is a competitive business and very proprietary. The FDA labeling requirements for flavors allow them to be listed generally as “spice,” “natural flavor,” or “artificial flavor” (or a combination of those). This makes tracking and standardizing public records of food fraud related to flavors challenging.

Our data includes more than 60 of food fraud related to flavors represented as “natural.” Most of these records are linked to vanilla extract or various essential oils. However, we have also captured a handful of records that address misrepresentation of synthetic flavor chemicals as naturally-derived. This includes records for linalool and ethyl butyrate, among others such as vanillin and linalyl acetate. However, none of these records describe publicly reported incidents of fraud for naturally-derived flavor chemicals. The records are based on peer-reviewed publications aimed at method development for authentication of natural flavors.

Added value claims such as “natural” tend to increase food fraud risk because the costs of production can be so much higher. While an ingredient like vanilla extract is certainly one example of this, we do not tend to see the same level of evidence of food fraud potential for naturally-derived flavor chemicals in public records. When our users need to conduct a food fraud vulnerability assessment for a natural flavor that is a proprietary blend of flavor chemicals, we suggest that they incorporate information from the entire natural flavors group into their assessment. Given the proprietary nature of flavor blends and FDA labeling requirements, it is not feasible for us to track every individual flavor blend in our database.

Fortunately, given the importance of flavors to the food industry, flavor companies have a vested interest in preserving their client relationships and public reputation by ensuring flavors labeled as “natural” qualify for that label claim.

Stored Product Insects Are Costly Consumers

How much can pest issues cost? The truth is, it changes based on the pest, the size of the population and the prevalence throughout your food processing facility and products. If you want to protect your bottom line, you need to know which pests are the biggest threat and take steps to prevent them. Let’s focus on one major threat to food processing facilities: Stored product insects.

Believed by some pest control providers to be the costliest pests for food manufacturing and processing businesses, stored product insects can put a huge dent in your profits. What’s worse, these pests can be tough to discover by an untrained eye, and they’re incredibly difficult to control without the help of a pest management professional.

According to the USDA and the University of Wisconsin, “stored product pests can damage, contaminate, or consume as much as 10% of the total food produced in the U.S. alone, while in developing countries that rate has been estimated at 50% or more.”

That’s an astronomical figure for such small insects! Can you imagine the impact on your bottom line if 10% of your product was ruined?

For any business in need of an updated prevention plan, the first step is to review the current integrated pest management (IPM) program to ensure a proactive approach has been implemented to monitor for, and react quickly to, any pest issues around the facility. There’s no one-size-fits-all strategy for an IPM program; each program should be customized to meet the needs of the individual business. Different geography, construction and food products being produced can all create different pest pressures.

According to another study conducted by CEBR on the impact of pests on the global food supply, disruptions caused by pest infestations resulted in $9.6 billion in operating costs in the countries surveyed and 84% of U.S. businesses reported a net impact on revenue due to pest infestation across a five-year period. Diving deeper, 28% of food manufacturers and processors reported pest-related costs associated with contamination of raw materials leading to replacement costs.

In other words, having stored product insects around is expensive. If there were ever any doubts about the value of a proactive IPM program, these statistics prove it. So, let’s take a closer look at how you can work to protect your business against stored product insect—some of the most likely and costly invaders.

Types of Stored Product Insects

The term stored product insect covers a range of insect species that can be broken up into three main subcategories: External feeders, internal developers and secondary feeders. Each category has its own distinct characteristics, which are important to know for detection and proper identification.

External Feeders

This group develops on the outside of products, including damaged grains and processed foods. As they feed, they damage product and leave behind frass (insect droppings) as they make their way through.

Some of the most common external feeders include Indian meal moths and flour beetles.

Adult Indian meal moths are roughly 9 mm long and have a wingspan of 14–20 mm. The front wings on the adults are bicolored, with two main tones: Reddish-brown at the wing tip and silver-grey at the base. If you don’t see the pest itself, you may notice a messy silk webbing spun by the larvae.

Red and confused flour beetles, two of the most common beetle species, are 3–4 mm in length and also have a reddish-brown color. They’re rectangular-shaped beetles and can often be found in grain bins infested with internal developers. This is because flour beetles like to feed on the kernels other stored product insects, like borers, have already broken up. They can also be found in processing lines and finished products.

Internal Feeders

Internal feeders lay eggs inside or outside of kernels of grain but develop entirely inside those kernels. As they develop, they hollow out the kernel, then the adults can go on to damage other kernels.

Some of the most commonly encountered internal developers are lesser grain borers and rice, maize and granary weevils. Weevils measure about 5 mm in length and are usually brown in color with a distinct elongated “snout.” Lesser grain borers, the most common internal feeder across the United States infesting wheat, are a bit smaller and don’t have the snout that weevils do. Both weevils and lesser grain borers have pitted patterns on their bodies, and all can fly except the granary weevil. As the larvae and pupae develop inside grain kernels, damage becomes especially evident when the adult chews out and leaves a distinctive perfectly round hole.

Secondary Feeders

This group typically eats from the outside in and feeds on the mold and fungus that can grow on out-of-condition grain and damp product.

Two of the most common secondary feeders are the foreign grain beetle and sawtoothed grain beetle. Foreign grain beetles love mold, and resemble flour beetles in size and color. To tell them apart, look for two “bumps” on the top corners of the thorax. Eliminating molds and damp conditions that facilitate mold growth is generally enough to help prevent infestations from secondary feeders.

Sawtoothed grain beetles can feed on many types of products and while they can’t physically penetrate packaging, the adults will find holes less than 1 mm in diameter, lay eggs, and the larvae will squeeze through the tiny openings to get to the product. They prefer processed food products like bran, chocolate, oatmeal and even pet foods, but will feed on whatever they can access. Sawtoothed grain beetles are smaller than flour beetles (3 mm) and have distinctive “teeth” on the margins of the thorax.

Prevention, Monitoring & Detection, and Removal

The best way to protect a facility from stored product insects is to employ numerous different tactics. Specifically, it’s important to proactively mitigate pest attractants, monitor for activity in key areas around the facility, and establish thresholds and action plans when pests are detected.

First and foremost, educate all employees about the pests most common around your facility and what to do should they spot one. Your pest sighting log is a great tool, but only if people use it! Have a clear escalation plan for any pest issues spotted. In addition, create a sanitation schedule to ensure all areas and equipment are cleaned to remove food and moisture buildup attractive to pests on a regular basis. While you can’t possibly eliminate all food (you are of course storing and processing food!), the aim is to minimize the amount and the access these insects have to that food source.

Next, make sure all incoming shipments and packages are inspected closely in a sealed off unloading area away from other products. Make sure employees know to check for signs of damage, especially holes caused by boring pests. Taking the time to inspect anything entering your facility in this way will give you a chance to spot pests before they have the chance to spread to your other products. Use the first-in, first-out (FIFO) approach for all goods to ensure older product doesn’t sit. The longer product sits, the more chance it can be infested and it may start deteriorating, and this is especially attractive to stored product insects.

For ongoing monitoring, talk to a pest management professional about deploying pheromone traps strategically around your facility. Pheromone traps are the best tool to monitor for stored product insects, as they will give you an idea of which pests are present, in what numbers, where they are, and they can help you track trends in pest activity over time. If any stored product insects are ever spotted, contact your pest management professional immediately. If there’s a chance of having stored product insects on your product, you absolutely should have pheromone trap monitoring in place.

The Total Cost of Stored Product Pest Problems

The impact of pest issues caused by stored product insects isn’t limited to the cost of paused operations and replacing contaminated product. These pests are tough to spot, and could be passed along to partners further down the supply chain. Naturally this could hurt the trust between supply chain partners, which is never a good thing!

If your facility gets a reputation of having problems with stored product insects, it’s going to hurt your brand—and that’s going to be another knock to your bottom line. Stored product insects can spread quickly between products placed closely together. So, if pests are mistakenly shipped to a partner’s facility or a store and then on to a customer, now THEY are going to have to deal with stored product insects, too. Being proactive is the best approach, and careful documentation can help you and your supply chain partners track pest issues to the source so they can be resolved quickly and minimize the impact on profits.

It becomes easy to see stored product insects can cause both short-term and long-term effects on the profitability of a business. Don’t let that be your facility and your reputation! Be proactive and partner with a pest management provider to help ensure your facility operations run smoothly and your customers stay happy.

What Should I Do if I Have a Foreign Material Problem?

By Chris Keith

Chris Keith, FlexXray

Imagine this: While cleaning a slicing machine during a sanitation break, one of your employees discovered a piece of harp wire was missing from the machine. The meat that had been sliced since the cutting machine’s last inspection had already been added to your product, and the product had been packaged. It had already passed through your company’s inline inspection machines without any foreign contaminants being detected.

You enjoy a spotless reputation in the food industry and know that if consumers lose faith in the product, it will suffer significant damage to both its reputation and its bottom line. So what do you do now?

Here’s a look at four different scenarios and how each one can affect a respected food manufacturer.

Option 1: Dispose of the Full Production Run

Disposing of a full production run will give your company complete confidence that the contaminant issue is resolved and will never reach the public. However, you have to take into consideration the full cost and implications of such a move, such as:

Where to dispose of the contaminated product. The FDA has specific rules about disposing of contaminated food products, but those guidelines can be affected by local, state and even federal regulations. Among the disposal options are landfills, rendering or incineration. You must find the proper facility, arrange the safe transportation of the product and procure all the required permits for the disposal.

Food waste. With 40% of the food produced in the United States going to waste, and 50 million Americans not knowing where their next meal will come from, you don’t want to add to the problem.

Product out of stock. Having your product out of stock will be costly. In addition to the lost sales, there’s a chance that consumers will turn to another brand—and not return to buying your product.

Cost of reproduction. To re-run the entire product line, you will essentially double your costs. You will have to pay for the cost of the products used, as well as pay for new packaging and all labor costs.

Option 2: Rework the Product In-House

You can use your own resources and inline equipment to try and troubleshoot the problem. Running the product through the metal detector to look for the harp wire could salvage most of the product, and would give your company the ability to supervise the entire process. That way, if you find the metal, you’d know firsthand that the contaminated product is out of production and won’t reach consumers.

But there are some expensive downsides to this approach. Among the factors that your company must consider are:

Loss of productivity. Both from the standpoint of equipment utilization and the productivity of employees, reworking the product would be costly to the company. You would have to have to slow the production line and manually re-run all the product through the metal detector to look for the missing wire.

Increased labor costs. You would have to pay overtime to your employees and keep your standard production line running while it re-runs the product and looks for the suspected contamination.

Limitations of their inspection equipment. Your results are only as good as the equipment you are using, and there’s always a risk that the metal detector that missed it the first time won’t find it the second time, either.

It seems like a bit of a gamble; if the metal detector catches it the second time around, then it could be worth it. If the product is re-run and no contaminants are found, however, your company is back where it started and must decide how to move forward.

Option 3: Risk It and Ship the Product to Retailers

Since the metal wasn’t detected by the company’s inline inspection system, you cannot be absolutely sure the metal is in the product. You only know that a broken piece of harp wire is missing; it’s unclear whether that wire made it into the food.

The least expensive option—but also the riskiest—is to go ahead and ship the product, hoping that the missing wire didn’t make it into the food and, therefore, never gets discovered by consumers.

There’s a chance that the metal detector was right, the wire isn’t in the food, and things will be fine. However, if the risky gamble doesn’t go in your favor, the consequences could be severe and this becomes the most expensive option of all. Among the risks the company faces are the following.

Costly recall. Food recalls are always expensive. According to a study from the Food Marketing Institute and the Grocery Manufacturers Association, the average recall runs up a $10 million tab in direct costs alone.

This includes the cost of notifying the supply chain and consumers, retrieving the product, storage, disposal and additional labor costs associated with having to perform all of these actions.

Possible litigation. Food recalls often are accompanied by lawsuits, and if the metal wire is eaten by a customer and causes injury, you could be held liable for everything from medical bills to time lost from work due to pain and suffering.

Bad publicity and lost sales. In today’s 24/7 news world and with the power of social networking, news of a food recall can reach consumers at lightning speed. This equates directly to lost sales and can have a negative impact on your brand reputation and market value.

A recent Harris Interactive Poll found that 55% of consumers would switch brands temporarily after a recall, and 15% would never buy the product again. What’s more, 21% said they would avoid buying any other products made by that manufacturer.

Option 4: Use an X-ray Inspection Service

A fourth option can help avoid lawsuits, recalls and bad publicity, while at the same time sidestepping unnecessary waste and the costs associated with disposing of an entire production run or reworking it internally.

You can have your product shipped to an X-ray inspection facility, or use an X-ray inspection rental service.

A contaminant removal service and professional catalog reporting with full traceability could also ensure that the specific contaminant was located and removed, and you would have the confidence that the problem had been resolved as the product reached consumers. There are several other advantages to using a company that offers this type of solution as well, including:

Reduced waste. Because the only product being thrown away would be the product that was contaminated, there would be minimal waste. This is the only option that allows you to recover the rest of the product, with the certainty that it has been inspected and is safe for its customers.

Advanced detection capabilities. You can be confident in inspection process using custom technology that enables the detection of foreign particles down to 0.8 mm or smaller. In addition to metal, such systems can also detect product clumps, glass particles, stones, bone, rubber, plastic, wood, gasket materials, container defects and missing components.

This type of solution far exceeds the capabilities of inline inspection machines, and, because it can run a single pallet an hour, instead of the average 10,000 pounds an hour, and thus it spends more time focusing on what is passing through the machine to ensure no contaminants pass through.

Final Thoughts

When it comes to the quality of your product, it’s better not to take any chances. When you put your product line in the hands of a third-party X-ray food inspection company, you know you will get results since food safety is our specialty — and it’s what they do, all day, every day.

Three Reasons your Restaurant Needs to Take Food Safety Seriously

By Courtney Bosch-Tanguy

Courtney Bosch-Tanguy

Food that is not only fresh and delicious but is also safe to eat is a must for any restaurant. Foodborne illnesses are a real threat to consumers and can permanently mar the reputation of the chain or restaurant who spreads them. If you’re at risk for serving up a chicken breast with a side of Salmonella or a burger crawling with E. coli, it is just a matter of time before someone gets sick. According to the CDC, about one in six Americans will get sick from a foodborne illness each year; more than 125,000 people per year become ill enough to be hospitalized.

Beyond the moral obligation to serve up quality food and to make sure your customers don’t get sick, attention to food safety can also prevent a public relations nightmare for your brand. The very mention of foodborne illness triggers a connection with Chipotle, even though many of the brand’s news-making outbreaks were over three years ago. Keeping customers, your business, and your reputation safe are just three reasons to incorporate food safety best practices into your daily routine.

Promote Customer Safety

You’re in business to serve your community or a specific population, so it is in your and their best interests to ensure the food you are serving up is not only tasty, but safe as well. Proper attention to everything from handwashing, to choosing the right cutting surfaces, to serving and storing food at the proper temperature, and properly labeling prepared foods and ingredients ensures you’re not harming the very customers you are trying to serve.

When you can be confident that your sanitation, storage and labeling process are the best they can be, you can serve every customer with pride, knowing you’ve provided them with the best possible meal or item. Your customers will know they can patronize your establishment with confidence that you take their safety seriously and are consistently dedicated to quality.

Protect Your Reputation

Chipotle, Taco Bell, and other brands found out the hard way: News spreads fast. In this era of smart phones and instant communication, that hair attached to your pasta is horrifying for more than just the patron who ordered it. With social media at the ready, one mistake could be broadcast to an audience of thousands in just seconds.

In 2015, Chipotle made headlines, for all the wrong reasons. The brand had outbreaks in multiple locations, spanning 11 states. Even after a public and thorough store sanitation and cleansing, consumers and media still question the level of food safety in the brand’s locations and how these outbreaks were handled by the company. Chipotle had a more recent incident this summer. The chain committed to retraining all of its restaurant workers nationwide on food safety after nearly 650 customers became ill from eating at one of its Ohio restaurants. Tests showed sickened customers had Clostridium perfringens, which is a foodborne disease that occurs when food is left at an unsafe temperature.

Taco Bell has been under investigation for foodborne illness multiple times in the past few decades, dating back to 1995. From Salmonella to E.coli, the brand continues to struggle with food safety, making it a frequent target of both the news media and comedians cracking jokes at the brand’s expense.

Protect Your Business

Chipotle suffered in more ways than one during that series of publicized outbreaks. The company’s stocks and profits plummeted, even after the outbreak appeared to be over. Jack in the Box never fully recovered after a tragic case of E. coli outbreak that resulted in the deaths of four children almost two decades ago.

Consumers have long memories, and there is no such thing as an isolated incident anymore. Focusing on food safety in this digital, social-media-powered era is more important than ever before. Simple steps, from properly training your employees about food safety, to implementing the right tools and technology to manage a food safety program, to properly labeling and testing food before you serve it, can help your brand maintain its sterling reputation and keep your customers safe.

Every step you take towards implementing proper food safety protocol is a step in the right direction for your customers, your business, and your reputation.

Today it was announced that FDA Deputy Commissioner for Foods and Veterinary Medicine Stephen Ostroff, M.D. is retiring and Frank Yiannas, vice president of foods safety at Walmart, will join FDA as the Deputy Commissioner for Food Policy and Response.

FDA Commissioner Scott Gottlieb, M.D. made the announcement in an email to agency employees. Yiannas will have a different title than Ostroff’s, which is reflective of the reorganization at the agency—FDA will reportedly be creating a new office called the Office of Food Policy and Response. Yiannas will also reportedly take on the role of senior scientific advisor to Commissioner Gottlieb on issues related to food safety and supply chain.

Ostroff will retire in January 2019 and will assist in the transition of Yiannas into his new role at FDA.

Tim Lozier, EtQ, Inc.

As business becomes more global, effective and efficient, supply chain management is more vital than ever. Even if you’ve optimized your supply chain, uncertainty can cause issues when sourcing raw materials, goods and services, which could ultimately impact on your business, customers, revenue and reputation.

Fortunately, forward-looking risk management can help you understand potential problems in the supply chain and allow you to create contingency plans or take mitigating actions. Supplier risk management will let you ensure quality at every stage, help you prepare for potential issues, and deliver goods and services to the quality and deadlines your customers expect.

An Overview of the Supply Chain

The supply chain is the process through which you source raw materials, goods, services and other key functions from your suppliers. It has multiple facets:

  • Identify the right suppliers and vendors.
  • Negotiate prices, terms and conditions.
  • Place orders with suppliers.
  • Arrange for transport of goods and services to your business or to other manufacturers.
  • Make payments to suppliers.
  • Receive products and services into your business for onward provision to end customers.

If you want to avoid problems and maximize quality throughout the supply chain, you will need to explore each of these areas.

Key Risks to Effective Supply Chain Management

Here are the main risks on the supplier side, and how to manage potential issues.

Poor Quality Supplier Challenges

Risks with poor quality suppliers include:

  • Goods, services and raw materials that do not meet your requirements.
  • Delays in sending out your orders.
  • Unreasonable demands made to your business.
  • Hidden, detrimental terms and conditions.
  • Damaged vendor relationships.

You can mitigate these risks through:

  • Getting recommendations from other organizations that are sourcing similar items or services.
  • Insisting on samples of the items you are planning to purchase.
  • Reading reviews of suppliers and feedback from other customers.
  • Ensuring you have robust contracts in place that clearly define the relationship.
  • Employing a vendor manager who can ensure that relationships and negotiations run smoothly.

Unexpected Prices or Supply Challenges

Risks with pricing and supply include:

• Volatile pricing and potential overcharging.
• Suppliers not being able to source and provide what you have ordered.

You can mitigate these risks through:

  • Locking in guaranteed pricing for specific areas and predefined lengths of time.
  • Auditing of invoicing and costs versus agreements and contracts.
  • Getting backup suppliers in place if your original supplier has a supply issue.
  • Guaranteeing with the supplier that they will hold a certain amount of inventory for your specific needs.
  • Insisting on regular reports of stock levels that you can draw down from.

Cultural, Environmental and Economic Challenges

Risks with culture, environment and the economy include:

  • Language and cultural barriers with suppliers leading to misunderstanding.
  • Local laws that impact on a supplier’s ability to meet your needs.
  • Environmental factors like natural disasters
  • Unstable political movements.
  • Societal unrest and conflict.

You can mitigate these risks through:

  • Getting backup suppliers in place if your original supplier has a supply issue.
  • Using local expertise to understand and deal with any potential legal or political issues.
  • Creating a contingency plan in the event of a natural disaster or economic issues.
  • Using a relationship manager who can understand and deal with differences in language and culture.

Transportation and Distribution Challenges

Risks with transportation and distribution include:

  • Inefficient logistics and distribution, leading to delays or loss.
  • Unexpected costs of transportation, import and export, including tariffs and customs.

You can mitigate these risks through:

  • Getting backup distributors in place if your original distributor has an issue.
  • Reading reviews of distributors and feedback from other customers.
  • Ensuring you have robust contracts in place that clearly define the relationship.
  • Understanding potential costs throughout the supply chain.
  • Creating a contingency plan in the event of supplier issues.

Examples of Supply Chain Risks and Issues in the Food Industry

Let’s dig into some potential risks to food supply chains, and how you might mitigate them.

Unusual Weather Patterns Lead to Smaller Harvests and Lower Yields
Food manufacturers rely on a steady supply of raw materials to make the products consumers eat every day. However, weather and climate can be anything other than predictable, and have several associated risks. Potential mitigation plans include:

  • Identifying early climate trends that could impact a region and seeking out alternative sources.
  • Having backup contracts with other suppliers if the crops from one region fail to meet appropriate yields.
  • Developing alternative products that use fewer of a particular type of raw material or ingredient.
  • Stockpiling vital ingredients in secure, long-term storage.

Tariffs Impact Import and Export Prices
Political uncertainty can result in increased customs tariffs to trade in certain goods. Potential mitigation plans include:

  • Importing or exporting a surplus of goods before the tariffs come into effect.
  • Seeking out alternative routes for food supply chains that do not go through impacted countries.
  • Diversifying into food production that’s not impacted by specific tariffs.
  • Moving part of manufacturing to regions not affected by tariffs.

Unexpected Production Issues Impact Food Safety
Food safety is critical to consumer confidence and a food manufacturer’s reputation. Despite stringent quality in the ingredient and manufacturing process, the global food supply chain can sometimes introduce contamination or other risks. Potential mitigation plans include:

  • Clear, objective, verified, regular testing of all raw ingredients, independent of origin, type or destination.
  • Labeling, batch numbers and other identifiers so all goods can be tracked through the supply chain to allow for easy identification of contaminant sources.
  • st recall process so any products that are in stores can be easily removed and returned for testing.
  • Exceeding FDA regulations and guidelines for safe food manufacturing.

When you’re managing risk in the supply chain, it is vital to capture all potential issues and prioritize them in terms of likelihood, impact and any other variables that are critical to your business. You can then get risk mitigation plans in place, and ensure your stakeholders and cross-functional teams have the resources they need to resolve your supply chain risks.

How Workflow Advances Raise the Bar in LC-MS/MS Veterinary Drug Quantitation

By Ed George
No Comments
magnifying glass

In the modern world, it’s often taken for granted that consumers can head to their local grocery store and fill their baskets with a broad range of meat, poultry, fish and dairy produce. Yet the plentiful availability of these products is possible, to a large extent, thanks to modern farming methods that rely on veterinary drugs to promote healthy animal growth, protect livestock from contracting diseases, and in some cases provide aesthetic qualities to food.

Despite the important role veterinary drugs play in farming and food production, usage must be carefully controlled, as their inappropriate administration can have adverse effects on animals, the environment and human health. A particular concern is the growing problem of antimicrobial resistance, which can be promoted in the environment by the overuse of some of these veterinary drugs.

As a result, the analysis of veterinary drugs forms an important part of routine food safety and quality control testing. However, the wide range of residue concentrations required to be quantified, along with the diverse sample matrices and chemical properties of multiple classes of veterinary drugs placed in a single analytical method, pose significant analytical challenges. The latest multi-residue, multi-class analytical workflow solutions using a generic sample preparation method and liquid chromatography tandem mass spectrometry (LC-MS/MS) are overcoming these issues to provide a robust, sensitive method for the extraction, detection, confirmation, and quantitation of veterinary drugs below their required maximum residue limits (MRLs).

Meeting the Needs of Veterinary Drug Analysis Workflows

Given the need to accurately and reliably quantify veterinary drugs in food, testing workflows must be both sensitive and operationally robust. Importantly, workflows must be amenable to a variety of different matrices, including meat, fish and dairy, and should be capable of screening for drug molecules with a broad range of physicochemical properties. The sample preparation protocols that are employed must minimize the loss of analytes and be sufficiently simple and cost effective to enable routine laboratory use. Additionally, the separation steps that are employed must be sufficiently rugged and should ideally be able to handle any analyte and matrix. Finally, the methods used to identify and quantify samples must be sufficiently selective and sensitive to detect and confirm drug molecules and their metabolites at trace levels.

Developing methods that can meet all of these criteria for a wide range of drug molecules and food matrices, while minimizing the potential for false positive and negative results, is not straightforward and has proven challenging for the industry. As a result, many analytical methodologies have emerged that are typically limited in scope to a limited number of residues or specific chemical classes, are labor intensive, and require extensive sample preparation and clean-up. Fortunately, ongoing advances in veterinary drug analysis workflows are helping to drive the adoption of standardized protocols that have universal applicability.

QuEChERS: Making Sample Preparation Quick, Easy and Reliable

Sample preparation is a key first step in veterinary drug analysis workflows, but its importance is often overlooked. Even with the most advanced downstream separation and detection technologies, workflows are liable to generate poor quantitative results without reliable residue extraction methods.Having robust sample preparation protocols is especially important given the heterogeneous nature of the sample matrix and the different physicochemical properties of the residues that must be extracted.

Traditional approaches, based on sample homogenization and multi-step solvent extraction procedures, were time-consuming and did not always produce consistent results. The loss of residues during sample grinding or through the formation of insoluble drug-matrix complexes would often impact the accuracy of measurements. Moreover, the need for labor-intensive sample cleanup steps, based on separation methods such as gel permeation chromatography, added additional complexity to workflows.

The widespread adoption of universal sample preparation protocols based on QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) methods has simplified the process of extracting veterinary drugs from matrix samples. These approaches have been specifically designed to be quick and easy to implement, and enable high extraction efficiency with a very broad range of chemical properties from a variety of matrices. As a result, QuEChERS has proven to be a very reliable means of preparing samples for veterinary drug analysis.

The universal suitability of the QuEChERS approach has reduced the complexity of sample preparation workflows to such an extent that many suppliers now offer kits containing pre-weighed reagents that can be used straight from the box. Moreover, because they only require small amounts of sample and solvent, and little in the way of equipment, these easy-to-use methods are helping laboratories minimize waste and make workflows more cost-effective.

Triple Quadrupole MS: Design Improvements Driving Exceptional Sensitivity

LC-MS/MS has rapidly established itself as the go-to technique for sensitive and reliable veterinary drug analysis, with set-ups based on ultra-high performance liquid chromatography (UHPLC) systems and triple quadrupole mass spectrometers proving to be particularly effective. With drug residues typically on the parts per billion scale, these systems have proven to be more than capable of delivering the level of performance that’s required when working with analytes that require low detection limits.

What’s more, recent advances in triple quadrupole mass spectrometer technologies are pushing the limits of quantitation even further. Improved instrument designs based on segmented quadrupoles, more powerful electron multipliers and enhanced ion transmission optics are enabling food analysis laboratories to achieve even greater levels of experimental sensitivity, mass accuracy, selectivity and precision. These performance improvements are allowing analysts to make more confident decisions around every sample.

The capabilities of the latest generation of triple quadrupole LC-MS/MS systems for quantitative veterinary drug analysis were put to the test in a recent study. More than 170 veterinary drugs were added directly to a variety of homogenized matrices, including bovine muscle, milk, and salmon fillet using a QuEChERS sample preparation protocol to create a series of matrix extracted spikes (MES). The concentration of residues in the MES samples referenced a chosen screening target concentration (STC), which was typically one-third to one-quarter of the defined European Union MRL for each residue/matrix combination. Figure 1 presents the total extracted ion chromatogram for an MES sample of salmon fillet at the STC, obtained with a binary UHPLC system and a triple quadrupole mass spectrometer.

For each analyte, calibration curves were constructed using replicate measurements of each of the MES samples at seven concentrations ranging from one-fifth to five times that of the STC.

the range 0.2 to 5.0 ng/g (STC = 1 ng/g). The calculated method detection limit of 0.03 ng/g for this compound in salmon fillet demonstrates confidence in the results well below the minimum required performance limit (MRPL).

LC-MS/MS: Leading the Way in Workflow Robustness

With potentially hundreds of samples to analyze every week, veterinary drug analysis workflows not only demand the highest levels of sensitivity, but also exceptional speed and robustness.
One way in which greater throughput can be achieved is by using shorter instrument dwell times, an experimental optimization that allows more compounds to be analyzed within a given timeframe during a chromatographic separation. Traditionally, the use of shorter dwell times would typically require sacrificing some measurement sensitivity. However, the latest advances in triple quadrupole instrument design are ensuring short dwell times no longer come at the expense of analytical performance.

Timed selected dreaction monitoring (SRM) is an effective strategy that allows analysts to overcome this challenge to achieve sensitivity with high throughput. Using timed SRM, data acquisition occurs within a short retention time window. This reduces the number of transitions that are monitored in parallel for each residue peak, while ensuring consistent quantitation even at low concentrations. Instrument control system software can automatically optimize the SRM conditions across the chromatographic run, maximizing operational efficiency with minimal need for manual input.

Instrument uptime is another factor that is of paramount importance for veterinary analysis workflows. With large workloads and tight turnaround times, regular instrument recalibration and frequent maintenance can be a major frustration for busy food testing laboratories. UHPLC is renowned for its operational robustness and suitability for fast-paced routine screening workflows, and the latest instruments are taking this reputation to an even higher level.

Figure 3 compares injections of bovine muscle extract at 3× STC over a 500-injection run that took place over a period of one week, obtained using the experimental set-up described earlier. Despite continuous operation over this extended period, the peak shape, intensity and retention time stability are maintained. These results further highlight the robustness of the LC-MS/MS system for routine veterinary drug testing.

Conclusion

Enforcing the responsible use of veterinary drugs in farming and food production depends upon comprehensive, sensitive, robust and reliable workflows capable of delivering quantitative results. Advances in sample preparation techniques and LC-MS/MS technologies are setting new standards when it comes to confident multi-residue veterinary drug analysis. From the development of reliable easy-to-use QuEChERS protocols, through to robust UHPLC separation methods and sensitive triple quadrupole mass spectrometers, improvements across the workflow are driving exceptional performance—whatever the matrix, whatever the residue.

FSMA and the Importance of Data Visibility and Management in Food Manufacturing

Data management, food manufacturing

Implementation of FSMA has prompted many organizations to take a closer look at sanitation practices, documentation of food safety plans and the traceability of materials and ingredients used to create food products.

Meanwhile, shifts in technology, such as cloud migration as well as the rise of big data and analytics platforms, present both opportunities and challenges in food manufacturing.

In many cases, digital transformation, including the adoption of a multi-cloud strategy, occurs as part of a roadmap set forth by a food company’s software vendors. Tech giants, including Microsoft, Oracle and SAP, are driving digital transformation through the modernization of ERP systems and dictating how food companies should utilize applications, data and software.

In those situations, digital transformation is not a choice, it’s a requirement. CIOs and IT professionals are seeking help. They are looking to understand the dynamics and characteristics of these new environments because they are compelled to change.

Yet, there are also organizations that would rather do more than simply follow the lead of their software vendors. Instead, they choose their own destiny in terms of IT modernization. They’re looking for opportunities by leveraging data to make better business decisions.

Before a food manufacturer can get to that point, however, there must be a strategy for gathering, storing, connecting and presenting different types of data across an organization as well as to external customers and business partners.

Managing the data required for FSMA compliance is an ideal example of the importance of pursuing digital transformation.

Food Safety Data and FSMA Compliance

A major component of FSMA involves having detailed documentation of a food safety plan and the ability to produce data proving adherence to that plan when the FDA shows up for a plant inspection. Food manufacturers need to show best practices are being followed, and that corrections are being made when concerns emerge. Otherwise, the FDA may impose fines or temporarily shut down production, which cuts into the bottom line.

Because of FSMA mandates such as the Sanitary Transportation Rule, your documented food safety plan needs to be communicated to key participants throughout the supply chain as responsibility for food safety problems typically falls back to the manufacturer.

For that reason, food processors need solutions allowing them to track and trace their product from the farm field to store shelves, or to any other final customer.

Imagine being a food manufacturer trying to document sanitation in a basic spreadsheet or even on paper. The extra work involved with specifying food safety tests, collecting and archiving results, and validating sanitation procedures would be overwhelming. Yet, just as perplexing of an issue is being a digitized food manufacturer with poor visibility and management of all the information that various IT systems and platforms provide.

Most companies acknowledge that the cloud is a necessity in today’s world. Organizations often need multiple cloud solutions to accomplish business objectives, from regulatory compliance to finances, inventory control and distribution.

CIOs, technology professionals and food safety/sanitation leaders should work with existing IT solutions partners or find consultants and experts who can ensure the following questions can be answered:

1. Is the location of your data known?

Data visibility in the cloud is the first step in the process, and it is a challenge for many organizations. You need to know where your data lives, that the right people have access to it and that it is secure. When you know where your data lives, you’ll better understand how to use and protect it.

2. Is your data in a location that allows for integration?

Can the different applications your company uses talk with each other, or is all the information siloed across different cloud providers and departments in the organization? Is it integrated? Can certain information, such as food safety plans, be communicated with partners including suppliers, distributors and your carrier network?

3. Can your data be put into a framework allowing it to be extracted, visualized and leveraged?

Data doesn’t help anyone if you’re unable to take that information and use it to make better business decisions. Whether it’s food safety, operational efficiency, forecasting needs or developing new ideas, the most successful food manufacturers will leverage integrated data to move the organization forward.

The Advantages of Pursuing Digital Transformation

If you were to go back about a decade and observed a small- to mid-sized food manufacturer using Microsoft as its data platform, that manufacturer would likely have been running applications for the business that created data while receiving little guidance pertaining to how the information should be interpreted and used. Fortunately, that has changed.

Today, companies like Microsoft, Oracle and SAP actively focus on the use of data rather than only data collection. The right IT solution, coupled with expert partners, allows you to eliminate the guesswork and leverage data to your advantage.

FSMA mandates are complicated, and compliance is crucial, but the pursuit of digital transformation supports the efforts of food manufacturers who are prepared to improve transparency and responsibility surrounding food safety.

Digital transformation represents change, which is never easy, but it will be worth the effort. Start by evaluating your organization’s technology needs as they relate to FSMA compliance as well as additional business objectives. Then, identify areas of internal strength and areas where improvements are needed.

Some food manufacturers partner with an IT solutions provider for support developing a cloud migration plan and a subsequent strategy for operating in multi-cloud environments. Others need managed services, helping them handle day-to-day IT needs through outsourcing so in-house resources can develop high-value solutions. Still, others are looking for consultative guidance to help them understand what changes in technology truly mean to their organization.

You want your people to focus on what they do best. Many food manufacturers are in locations where there’s a lack of technical resources for hire. That’s why they turn to IT consultants and service providers who understand their business, can provide expertise that fills the talent gap and are able to interpret business needs into technology solutions.

Digital transformation isn’t one big project, it’s an ongoing journey, a series of waves of new technologies and new ways to use applications and data. Make sure you find trustworthy allies to give you the guidance and solutions you need, not only for regulatory compliance but for growth and continued success.

Recall

The meat industry has been on alert over the past few days, much of which has been due to Salmonella and Listeria concerns. The following are the Class I recalls that have hit:

  • JBS Tolleson, Inc. recalls 6,937,195 pounds of raw non-intact beef products over concerns of Salmonella Newport contamination. According to the CDC, there are currently 57 reported cases across 16 states. No deaths have been reported. A traceback investigation involving store receipts and shopper card numbers enabled FSIS to trace the reported illnesses to JBS “as the common supplier of the ground beef products”.
  • Johnston County Hams recalls more than 89,000 pounds of RTE deli loaf ham products over concerns of adulteration with Listeria monocytogenes. The CDC and other health agencies are monitoring the outbreak, which has thus far infected four people, and one death has been reported. Recalled products were produced between April 3, 2017 and October 2, 2018. Also connected to this event is the recall of Callie’s Charleston Biscuits, which may contain ham from Johnston County Ham.
  • Canteen/Convenco recalled more than 1700 pounds of RTE breaded chicken tenders with BBQ sauce and hot sauce. The products were misbranded, as they may contain milk, and this was not declared on the finished product label. Thus far there have been no reported cases of adverse reactions due to consuming the products.
  • Ukrop’s Homestyle Foods has recalled more than 18,200 pounds of RTE meat and poultry deli-sliced products over concerns of product adulteration with Listeria monocytogenes. The products were produced and packaged from September 14–October 3, 2018. No confirmed illnesses have been reported to date.

The Power of Advanced NGS Technology in Routine Pathogen Testing

The food industry is beginning to transition into an era of big data and analytics unlike anything the industry has ever experienced. However, while the evolution of big data brings excitement and the buzz of new possibilities, it also comes coupled with an element of confusion due to the lack of tools for interpretation and lack of practical applications of the newly available information.

As we step into this new era and begin to embrace these changes, we need to invest time to educate ourselves on the possibilities before us, then make informed and action-oriented decisions on how to best use big data to move food safety and quality into the next generation.

Stephanie Pollard will be presenting “The Power of Advanced NGS Technology in Routine Pathogen Testing” at the 2018 Food Safety Consortium | November 13–15One of the big questions for big data and analytics in the food safety industry is the exact origins of this new data. Next Generation Sequencing (NGS) is one new and disruptive technology that will contribute significantly to a data explosion in our industry.

NGS-based platforms offer the ability to see what was previously impossible with PCR and other technologies. These technologies generate millions of sequences simultaneously, enabling greater resolution into the microbial ecology of food and environmental surfaces.

This represents a seismic shift in the food safety world. It changes the age-old food microbiology question from: “Is this specific microbe in my sample?” to “what is the microbial makeup of my sample?”

Traditionally, microbiologists have relied on culture-based technologies to measure the microbial composition of foods and inform risk management decisions. While these techniques have been well studied and are standard practices in food safety and quality measures, they only address a small piece of a much bigger microbial puzzle. NGS-based systems allow more complete visibility into this puzzle, enabling more informed risk management decisions.

With these advances, one practical application of NGS in existing food safety management systems is in routine pathogen testing. Routine pathogen testing is a form of risk assessment that typically gives a binary presence/absence result for a target pathogen.

NGS-based platforms can enhance this output by generating more than the standard binary result through a tunable resolution approach. NGS-based platforms can be designed to be as broad, or as specific, as desired to best fit the needs of the end user.

Imagine using an NGS-based platform for your routine pathogen testing needs, but instead of limiting the information you gather to yes/no answers for a target pathogen, you also obtain additional pertinent information, including: Serotype and/or strain identification, resident/transient designation, predictive shelf-life analysis, microbiome analysis, or predictive risk assessment.

By integrating an NGS-based platform into routine pathogen testing, one can begin to build a microbial database of the production facility, which can be used to distinguish resident pathogens and/or spoilage microbes from transient ones. This information can be used to monitor and improve existing or new sanitation practices as well as provide valuable information on ingredient quality and safety.

This data can also feed directly into supplier quality assurance programs and enable more informed decisions regarding building partnerships with suppliers who offer superior products.

Similarly, by analyzing the microbiome of a food matrix, food producers can identify the presence of food spoilage microbes to inform more accurate shelf-life predictions as well as evaluate the efficacy of interventions designed to reduce those microbes from proliferating in your product (e.g. modified packaging strategies, storage conditions, or processing parameters).

Envision a technology that enables all of the aforementioned possibilities while requiring minimal disruption to integrate into existing food safety management systems. NGS-based platforms offer answers to traditional pathogen testing needs for presence/absence information, all the while providing a vast amount of additional information. Envision a future in which we step outside of our age-old approach of assessing the safety of the food that we eat via testing for the presence of a specific pathogen. Envision a future in which we raise our standards for safety and focus on finding whatever is there, without having to know in advance what to look for.

Every year we learn of new advancements that challenge the previously limited view on the different pathogens that survive and proliferate on certain food products and have been overlooked (e.g., Listeria in melons). Advanced NGS technologies allow us to break free of those associations and focus more on truly assessing the safety and quality of our products by providing a deeper understanding of the molecular makeup of our food.
